Melbourne forward Mitch Clark has been granted indefinite leave from the club to deal with his personal health.

The Demons will continue to work with the key forward and his doctors, with no time frame in place for his return.

The former Brisbane Lion has battled foot issues since joining the Demons two years ago. He has not played a senior game since round four last season and has battled a calf injury through the pre-season.

In a statement on Saturday night, the Demons said Clark had been granted leave ''due to health reasons''.

''The club will continue to be in regular contact with Mitch throughout this period and is working closely with medical staff regarding his ongoing treatment,'' the statement said.

''Some of the challenges Mitch is facing may require some time to overcome and, as a result, he will be away from the club for an extended period of time.''
